Abstract concepts are hard to show
Pythagoras, induction, reactions: with chalk and talk students can’t picture them, and teachers don’t know animation software.
K12 AI Teaching Assistant:One Sentence from a Teacher Becomes Animations, Grading and Model Lessons
Teachers know how to teach, but turning a lesson into animation, checking every step of a class’s homework and building model courses to a standard takes more time and tech skill than one person has. Generic AI tools make teachers learn prompting, so schools struggle to roll them out.
We build subject components and fixed workflows into the system. A teacher types one request; the system breaks down the concept, applies animation components and generates a step-by-step explainer. Homework photos are checked step by step, and veteran teachers’ recordings become digital-human model lessons. It connects to leading LLMs, is tailored by school and subject, and can run on the school’s own servers.

01CHALLENGES
Where this work usually gets stuck today
Grading stops at right or wrong
With dozens of papers, teachers can only tick or cross; they can’t see which step or concept each student got stuck on.
Model courses never get built
Veteran teachers’ best methods live in the classroom; turning them into standard courses, slides and exercises drags on for a term.
02WHY AI
How an AI tool platform solves them
One sentence, one animation
The system splits the concept into steps and applies prebuilt subject components, so maths, physics, chemistry and geography principles animate step by step.
Grading down to each step
Photographed working is checked step by step, errors are tied to steps and concepts, and follow-up exercises match the class’s error pattern.
Experience becomes model lessons
Lesson recordings are analysed, teaching methods distilled and organised to model-course standards, with digital-human videos, slides and exercises.
No prompting to learn
Components and workflows are ready-made, so teachers see a few buttons and one input box. Models are swappable and data can stay on campus.
03WHAT IT DOES
What the platform does
Concept explainer animations
Type “explain Pythagoras” and get a stepwise animation of squares on each side fitting together, ready for class.
Stepwise grading and variants
Upload working, see error steps and concepts, get a class error summary and auto-generated variant exercises to choose from.
Digital-human model courses
With consent, a veteran teacher’s photos create a digital human that presents the organised script, with slides and exercises.
Shared district resource libraries
Deployed by the bureau, so animations, lessons and exercises from every school are filed by grade and subject and shared district-wide.
04HOW IT WORKS
How it works
Each step comes to you for approval before we move on.
- STEP 01
Try one lesson first
Pick a subject and concept, or a few real homework sheets; we build a demo so teachers can judge it first.
- STEP 02
Agree features and hosting
We agree which features, subjects and grades come first, cloud or on-premise, and confirm a feature list and screen designs with you.
- STEP 03
Build components and system
We build curriculum components and workflows, connect the models and build the teacher interface, piloting each part with a few teachers.
- STEP 04
Training, launch, upgrades
We train teachers, then add components and newer models based on feedback, so the system grows with your teaching.

07FAQ
Frequently asked questions
- Do teachers need AI skills?
- No. Components and workflows are built in; teachers type a request or upload a photo, and one onboarding session is enough.
- Will student data leave the school?
- The system can run on the school’s or bureau’s own servers so homework and grades stay local; cloud setups get access control and anonymisation.
- Can we start with one feature?
- Yes. Most start with explainer animation or grading, then add model courses and the resource library; subjects can be added one at a time.
- How soon can we use it?
- We first demo it on one of your lessons, then schedule by features and subjects. Message us on WeChat and we’ll send an approach and quote within 1–2 working days. Rush mode is available; timing and price are agreed separately.
